That's what I'm not sure of, like where would something like public blogs have appeared in the past? I know the private version is basically a journal or diary, but I'm not as sure if those were sometimes more publicly shared in the past or not.
To be more specific, by blog I'm thinking like personal, individual writings on whatever they happened to be thinking about or interested in.
Would there be any sort of logs either from the systems used to move the satellite, or aboard the satellite itself, to help answer the who question, if nothing else?
